first it depends on what you want to do. You can do programming, computer engineering or work with customers who buy the technology by selling or post sales and setting up the customer with what they bought.
Generally 4 year universities are a good place to start when looking at the best technology schools. There’s MIT, Stanford, Harvard that are expensive and very competitive to get into. Then there’s a hidden gem like San Jose State that is in the heart os Silicon Valley that is close to Stanford and 1/2 the cost. SJSU is a great school.
Hope this helps.
